We've seen him in a couple of concept art before and most of us have played him a couple of times in WC3 DotA but we can finally have a go at Juggernaut in Dota 2 as the latest patch has added him into the hero pool.
As usual, the latest patch was rolled out today with various bug fixes and improvements. But the most exciting addition is that Juggernaut is now playable. For those who are not in the beta yet, here are a couple of screenshots.
Full Patch logs available below as well.
